Title: Optical fibre monitoring
Inventor: LEWIS JOHN DIDWITH
IPC: G01M11/08
Filed: 1989-09-29
Abstract: A "clip-on" device for detecting the presence of a light signal in an optical fibre F includes bending means, eg a conical mandrel 1, for controllably causing a gradually increasing amount of deformation of a portion of fibre and a first detector 7 for detecting light escaping therefrom. A second detector 8 detects when the fibre has been subjected to a predetermined maximum amount of deformation. If light is detected by first detector 7 a signal is sent to control unit 9 which stops the bending means 1 from applying further deformation and gives a first output indication. If the second detector 8 detects that fibre deformation has reached the predetermined maximum amount and no light signal has been received, a signal is sent to control unit 9 which stops the bending means 1 from applying further deformation and gives a second output indication. <IMAGE>

Title: Process for the selective deposition of thin diamond film gas phase synthesis
Inventor: INOUE TAKAYOSHI
IPC: H01L21/20
Filed: 1990-01-09
Abstract: Thin diamond films are selectively deposited imagewise on a substrate by gas phase synthesis. The substrate may be either a silicon substrate or a basal thin diamond film formed beforehand on a substrate by gas phase synthesis. Where a silicon substrate is used, its surface is i) first abraded to give a surfaee roughness suitable for gas phase synthesis of diamond followed by ii) coating a uniform photoresist layer; iii) exposing the photoresist layer imagewise to illumination; iv) developing the thus-exposed photoresist layer, whereby exposed areas and unexposed areas are distinguished from each ether and the photoresist layer is eliminated in the exposed or unexposed areas; v) subjecting the surface of the silicon substrate in the areas, from which the photoresist layer has been eliminated, to reactive ion etching by a gas mixture discharge of CF4, Ar and O2; vi) dissolving any remaining photoresist layers; and vii) carrying out gas phase synthesis of diamond. When a basal thin diamond film is used, a coating material having a withstandable temperature higher than a substrate temperature required for gas phase synthesis of diamond and having a high etching selectivity to diamond eg amorpheus silicon is needed to cover areas other than areas where new thin diamond film is to be formed. In this embodiment the suriace is coated with a photoresist lithography, amorphous silicon is deposited over entire surfaces, the photoresist layer is lifted thereby producing a coating of silicon in those areas ether than where diamond is to be formed, and diamond is thereafter deposited in the gaps and the silicon depositss are removed. In a further embodiment a thin masking film having a melting point higher than a temperature to be employed for gas phase synthesis of diamond, eg amorphous silicon again, can be used to partly mask the surface of a basal diamond film by first applying the silicon over the entire surface, covering this layer with a photoresist layer by lithography in areas corresponding to where diamond is not to be deposited, eliminating the silicon in the areas not covered by the photoresist, producing a patterned silicon layer and depositing diamond in a pattern conforming with the intended surface areas of the basal thin diamond film. The silicon layer may then be removed. The coated products will find use as heat sinks, insulators in integrated circuits, semiconductor devices and optical waveguides.

Patent GB-913874-A (GB)
Abstract: 913,874. Starting prime-movers. C.A.V. Ltd. May 25, 1961 [June 1, 1960], No. 19347/60. Class 38 (4). Engine-starting apparatus generally similar to that of Specification 742,024, is provided with a relay arranged to break the circuit to the solenoid, and thereby de-energize the electric motor, after the solenoid has been energized for a predetermined period of time. The relay 9 has oppositely-acting windings 11, 12 and a capacitor 13 in series with the latter, the combination being connected through a diode D to the field coils 10 of the motor 3. In operation the solenoid 6 is energized by a manually-operable switch 7 to move the motor sleeve axially for effecting initial engagement of the pinion with the engine wheel. This movement closes the switch 4 and energizes the motor at low power through a resistor 8, the resulting slow motor movement closing the switch 5 just prior to full engagement of the pinion and wheel to short-circuit resistor 8 and operate the motor at full power. As soon as the engine has started, switch 7 is released and the various parts are restored by springs. When the switch 7 is closed current (insufficient to energize the motor) flows through relay 9, the windings 11, 12 neutralizing each other until capacitor 13 is fully charged, whereupon the relay is energized to open contacts 14 and deenergize the solenoid 6. The operating time of the relay is chosen to be somewhat greater than the normal time taken for the starter to become fully engaged, so that if the engine fails to start and the switch 7 is held closed the solenoid will be automatically de-energized, whereafter the starting operation is recommenced. The relay may be fitted to apparatus in which the complete assembly of the motor armature and pinion moves axially and the solenoid acts directly to close the first switch, the motor having shunt and main and auxiliary series windings, of which the latter serves a similar purpose to the resistor 8, Fig. 2 (not shown).
